Spend more than a few minutes outside any major U.S. airport and you'll see dozens of shiny black livery cars waiting to pick up arriving bigwigs. Look closer and you'll discover most of them are virtually identical to the 2011 Lincoln Town Car. That's because this grande dame of the Lincoln lineup hasn't had a major mechanical redesign in, well, decades. Which, oddly enough, is both this full-size luxury sedan's greatest strength and fundamental weakness. On the plus side, the Town Car is one of the few remaining sedans on the market to offer seating for six passengers. Rear-seat legroom is abundant, especially in the 6-inch-longer "L" body style. Other benefits of driving a car that's roughly 18 feet long include a downright cavernous trunk and excellent crash test scores. The downsides of the Town Car's anachronistic nature become readily apparent from the driver seat. The combination of its body-on-frame design and a solid rear axle contribute to the car's lackluster handling and nautical ride quality. The 239-horsepower 4.6-liter V8 and four-speed automatic transmission are about as outdated as you can get, delivering both poor fuel economy and meager acceleration.
